RAILROAD ACCIDENT REPORT. DERAILMENT OF PENN CENTRAL FREIGHT TRAIN B-4 AND COLLISION OF SOUTHERN RAILWAY PASSENGER TRAIN NO. 6 WITH DERAILED CAR AT ARLINGTON, VIRGINIA, APRIL 27, 1972

The document describes a passenger train-freight car collision at the Potomac Yard. The National Transportation Safety Board determines that the probable cause of the derailment of the freight cars was a defective rail, which broke while the train was passing over it. The probable cause of the collision between the passenger train on the adjacent main track and the derailed B-4 freight car was that the crewmembers of B-4 did not flag the passenger train as they were required to do by the operating rules.
